WATER-DEACTIVATIN G APPARATUS.

`Application filed May 16, 1927. Serial No. 191,718.

` This invention relates to water deactivating apparatus and has for its object the provision of animproved apparatus of this class in which finely divided ferrous or other corrodible metal isused as a deactivating material. n

A further object is to provide an apparatus of this class in which the. deactivating metal may be `readily charged and dischar ed by ordinary or unskilled labor.

Ot er objects and advantages will be brought out in the following specification.

In the drawings-f p n Figure 1 is a vertical sectional view through a deactivating apparatus constructed in accordance with my invention. Figure 2 is a top plan thereof. Figure 3 is a bottom plan thereof. Referring more particularly to the drawings, the numeral 2 designates the deactivating tank shell which has a head 3 and bottom 4 riveted or otherwise secured therein. rlhe head 3 is provided with a manhole opening 5 through which the deactivating metal 1s charged. A manhole closure or plate 6 is provided for normally closing the opening 5 and is adapted to be locked in closed position by a yoke 7 carried on a bolt 8 and a nut 9, which is threaded on the bolt 8 and adapted tobe screwed down a ainst the yoke 7 to draw the plate 6 tight against the head 3. The bottom 4 is provided with a discharge opening 10 for the used or spent deactivating metal, which opening is normally closed by a hinged cover or plate 12. The plate 12 is provided With slotted ears 13 at spaced intervals around its periphery which fit around or over hook-shaped lugs '14 when the cover plate 1s in closed position and wedges 15 are adapted 4o to be driven home between the hooked ends of `the lugs 14 and the ears 13 to lock the plate in closed position.

A sectional frusto-conical grid 16 is mounted in the lowei` end of the tank with its lower end positioned around the periphery of the discharge opening 10 and its upper edge in contact with the side walls of the tank, so that a space 17 is left around the grid 16 toreceive the deactivated water. l

The tank 2 is adapted tobe illedfor the major portion of its heightwith nely divided steel chips or turnings or other finely l divided or crushed corrodiblemetal having an aflinity for the dissolved oxygen in the water, as at 18. Preferably a length of chain, or other flexible member 19, having a plurality of metal disks 2() thereon, will be mounted centrally in the body of material 18 so that when it is desired to discharge such material the central portion of the body may be disturbed or broken up by moving the chain 19 upwardly therethroug y The water to be deactivated is adapted to How from a feed pipe 21 through a branch 22 into a heater indicated at 23, thence through a pipe2-l into the upper end of the ltank 2. The water will flow or seep down through the body of metal 18 and through the grid 16 into the space 17, from which it may he withdrawn through the outlet pipe 25, or, if no water is being withdrawn, it will pass out through the recirculating pipe 26 which connects with the branch pipe 22 leading to the heater. n i

A valve 27 is provided in the pipe 26 to permit the closing of this pipe, if desired, and

a check-valve 28 is also provided in the pipe If, as is sometimes theA case, the metal 18 is corroded so as to forni a more or less spongy mass or unit so that it will not fall out of the tank, the manhole cover or plate 6 is opened and the chain 19 moved upwardly so as to disturb and break up the center of the mass of metal and permit it to be readily discharged.

After the spent metal isdischarged, the

bottom closure 12 is replaced, lthe tankis reiilled with a new charge of metal, and the manhole cover 6 is replaced, again placing the apparatus in condition for use.

In some cases it may be found necessary to vating apparatus, they are not shown in this4 application.

While I have shown and described one specific embodiment ofmy invention, it will be understood that Ido not Wish to be limited g thereto since various modifications may be made Without departing from the scope of my invention as defined in the appended claims.' The Water may be passed through the heater and upwards through the scrap metal in the `deactivating tank 2 when desired by making suitable changes in the arrangement ot' the valves and piping, and other modiiications may be made.

I claiml. A Water deactivating apparatus comprising a tank having an inlet opening at one end for the admission of the deactivating material and an outlet opening at the other end for the discharge of the used deactivating material, removable closures for said openings, a truste-conical grid in the discharge end of said tank, said grid having its smaller end open and communicating With said outlet opening ot said tank and having the peripheral edge of its larger end engaged with the side Walls ot' said tank, thereby leaving a` space between the side walls of said grid and said tank for the collection oi' deactivated ivater, an inlet at one end of said tank :tor Water to be deactivated, and an outlet for the deacti 'ated Water aty the other end ot said tank and communicating with the space between the side walls ot said grid and said tank. 4

2. A Water deactivating apparatus comprising a tank having an inlet opening at one end tor the admission of the deactivating material and an outlet opening at the other end 'for the discharge of the used deactivatin g material, removable closures for said openings, a truste-conical sectional grid in the discharge end of said tank, said grid having its smaller end open and communicating with said outlet openinfr of said tank and having the peripheral e ge ot its larger end engaged with theside Walls oiz said tank, thereby leaving a space between the .side Walls of said grid and said tank for the collection of deactivated Wat-er, an inlet at one end of said tank for water to be deactivated, and an outlet for thedeactivated water at the other end of said tank and communicating with the space between the side walls oi said grid and said tank,

3. A water deactivating apparatus comprising a tank having an inlet opening at one end tor the admission of the deaclivating material and an outlet opening at the other end 'for the discharge of the used deactivating material, removable closures for said openings, a truste-conical grid in the discharge end ot said tank, said grid having its smaller end open and communicating with said outlet opening ol said tank and having the peripheral edge ot itslarger end engaged with the side walls oit'` said tank, thereby leaving a space between the 'side Walls of said grid and said tank for the collection of deactivated Water, a body ot finely 'divided deactivatin material filling the major portion of said ta i above said grid, a flexible disturbin Y clement mounted centrallyin said bodyot eactivating material and adapted to be moved out of said material prior to the discharge of said material so as to disturb or loosen said material and Jfacilitate its discharge, an inlet at one end of said tank for y'water to be deactivated, and an outlet for the deactivated water atjthe other' end of said tank and communicating with the spacebetwcen the side walls of said grid and said tank; i
